What to do about coal ash?

Here’s a little video I did two years after the “Christmas coal ash spill” in Tennessee. The long and the short of it is we still don’t know what to do with all the ash leftover after our coal burning. And, unlike CO2 and other air pollutants, coal ash doesn’t get a lot of attention. But all of our pollution controls are, essentially, moving the problem of pollutants from our air (via smokestacks) to our water (via leaching from coal ash).
